CHARLES MONDENG, OF MINNEAPOLIS, MINNESOTA.

HONEY-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 655,938, dated August 14, 1900. Application filed September 1, 189 9. Serial No. 729,157. (No model.)

To on whom it may concern:

Be it known that I, OHARLns MONDENG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Honey Box Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it' appertains to make and use the same.

My present invention relates to a machine for making honey-boxes or so-called honeyboX sections, and is in the nature of an im provement on the machine disclosed and claimed in my Patent No. 629,167, issued of date July 18, 1899, entitled Honey-box machine.

The primary object sought to be attained by my present invention by way of improvement over my prior machine is increased speed or efficiency. My said prior machine, While efficient and as rapid as any prior machine of the same character, was not capable of the maximum possible speed of an ideal machine for the above purpose.

By my present invention I believe I have accomplished practically a maximum or highest possible speed of which a machine of this character is capable, this result being attained by so timing and exposing the various cutters and other parts that no time is lost during the short intervals required by the operator to collect and present the blank strips to the machine.

The above features and others will clearly appear from a consideration of the machine herein illustrated and presently to be described.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a plan view of the machine con structed in accordance with my invention. Fig. 2 is a left side elevation of the machine. Fig. 3 is a rear end elevation of the machine, some parts being broken away and others removed. Fig. 4 is a horizontal section taken approximately on the line 03 56 of Fig. 5. Fig. 5 is a longitudinal vertical section taken approximately on the line 0: $85 of Fig. 1; and

Fig. 6 is a view corresponding in the line of its section to Fig. 5, but showing only the rear end portions of the said parts shown in Fig.

5, and certain of the parts being shown in cooperation with the said bed-plate of longitudinally extended end guides a? a and overhead guides at. The end guides a are par allel,and in line with the innersurface of each is a small circle-saw I), both of which saws are carried by a transverse shaft 17', suitably mounted in bearings 19 on the side brackets a and provided with a pulley 12 over which a belt (not shown) is run to impart motions to said saws. There is but one of the guidesurfaces a and this extends outward from the adjacent saw b. At the opposite side of the machine from that at which the guide a is located the machine-frame is left open, so thatthe blank strips from which the boxsections are made maybe readily introduced endwise into the horizontal guide-channel a, just in front of the saws b.

Mounted to reciprocate with a long slow stroke Within the horizontal guide-channel e forward of the saws b and interlined therewith is a transversely-extended feed-head c, which is of such length that it will pass between the saws b, as hereinafter described. As shown, the feed-head c has depending racks c, with which spur gears c on a transverse shaft 0 are in mesh. Said shaft 0-? is mounted in suitable bearings in the side brackets a,'and it is provided at one end with a pinion 0 which is engaged and operated as hereinafter described.

Just to the rear of the saws b are several spring-catches, which serve to prevent the IO fare of the proper form to cut the bee-en- ,one at each side of the trance screws in the edges of the box-sections, the lower members being mounted to work through openings f in the bed-plate a, while the upper members are mounted to Work through openings f formed in each of the overhead guides a Rearward of the cutting-toolsf and located machine, being mounted within suitable bearing-brackets g on the side brackets a, is a pair of vertical shafts or saw-mandrels g, which are provided with pulleys g over which power-driven belts (not shown) are run to impart motion to the said shafts. At their upper ends the said shafts or mandrels g are provided with vertically-spaced saws 9 that project through the sides of the guide-channel a far enough to engage the ends of the box-sections which are fed past them, and thereby to form in the ends of the said sections the tongue-andgroove connections.

At its delivery end the horizontal guidechannelzis curved and then extended vertically downward, this continuation, as shown, being formed by a pair of parallel channelstrips 7r, turned with their flanges inward, so as to embrace the ends of the partially-completed box-sections and to thereby guide the same for flatwise movement downward onto a shelf or table 0. which is supported between the rear ends of the side brackets a. The lower ends of the guide channels or strips are rigidly secured to the table or shelf a, and a narrow slit or opening 7:, is formed in the flanges of said guides 70 just above the table a these slits being just wide enough to permit the cut box-sections to be ejected one at a time. The boxsections are ejected one at a time by the action of a plunger or ejector m, which is mounted in suitable guides on said shelf a and is provided with a thin lip or blade m, which works through the said slits k. The plunger or ejector m is reciprocated froma pitman m pivoted thereto at one end and provided at its other end with an eccentric-strap 071 which works on an eccentric m carried by a transverse counter-shalt m suitably mounted in the side brackets ct. This shaft m is provided with a pulley m (shown only in Fig. 3) over which a'power-driven belt (not shown) runs to impart motion to said shaft and the parts driven thereby.

At one end the shaft m carries a sprocket m Standing in line with the sprocket m and suitably journaled at n" on one of the framebrackets to is a large sprocket n, which carries a crank 77. A sprocket-chain n runs over the sprockets m and n. The crank n is pivotally connected to one end of a rackbar of, the teeth of which engage the teeth of the pinion c heretofore noted as being carried by the counter-shaft 0 As shown, the free end of the rack-bar n is supported and guided in proper line for engagement with the pinion c by a keeper-bracket n and an ani-ifrictionroller n Mounted in suitable bearings 19, which are adjustably mounted on the rear ends of the frame-brackets a by means of set-screws p, is a transverse shaft or tool-mandrel 19 which carries V-shaped cutters 17 The V-shaped cutters p are adapted to cut the cornergrooves at three different points on the boxsections as they are ejected by the ejector or discharge-head m m. This shaft 19 is provided with a pulley 19 over which a powerdriven belt (not shown) is run to impart motion to said shaft.

At one side and at the intermediate portion of the downturned extension of the guidechannel z is a retaining-spring If, one end of which is secured to one of the channel-guides 7c and the other end of which normally projects inward,as best shown in Figs. 3 and 5. Mounted for vertical movement in suitable guides formed in each guide-channel k is a sliding block or carrier 25, which is normally held upward to its limit by the tension of a spring 1?. Each blocktcarries atrip-springfi, which has an extended finger t and an int-urned lip t, which lip projects into the guide-channel in position to engage the ends of a box-section which has been dropped onto the same. Normally the parts just noted stand as indicated in Figs. 3, 4, and 5.

Extending transversely of the machine and in line with the fingers t of the trip-spring t is a sectioned plunger 25, mounted in suitable bearings 25 on a transverse bar 15 which is secured to the guide-channels k. Springs t normally force the plunger-sections t inward or together. The said plunger-sections are forced outward or separated by a wedge 25 guided by'a keeper i and moved by a camlever 6 which is suitably pivoted or supported at 25 and is subject to the action of a cam 25 carried by a shaft 29 which shaft 29 is driven by and movable with the sprocket n and crank n heretofore noted. The relative position of the cam i and its timed action on the cam-lever 25 will appear in the description of the operation. As shown, a pair of leaf-springs t project from a transverse bar 25", which connects the lower rear portions of the guide channels k. These springs t serve to hold the box-sections fiat against the table a while they are being ejected and acted upon by the corner-grooveforming cutters p The operation of the machine above described, briefly summarized, will be substantially as follows: The blank strips from which the operator and placed side by side, the nu mber varying at different times. No exact number is necessary as long as the capacity of the machine, which would usually be twenty or twenty-five ata given feed movement of the feed-head c, is not exceeded. Ordinarily a small number would, of course, be gathered and fed at one time to the machine. The strips collected and placed side by side are moved endwise and transversely of the machine just in front of the saws b and just to the'rear of the feed-head 0, their inward movements beingli'mit-ed by the guidesurface a Each rotation of the sprocket n and crank n gives the feed-head one complete feed-stroke and return movement, and each feed movement of the said feed-head will carry all of the strips fed thereby to the rear of the saws b, so that the box-sections are thereby cut to the proper length and deposited between the parallel end guides a As other box-sections are cut off and fed into the guide-channel z the sections previously cut will be forced onward a distance corresponding to the total thickness of the sections fed in by the last feed movement of the head 0. As the box-sections are fed sidewise past the cutters f the bee-entrance grooves will be formed, and as they are forced still farther onward the saws 9 will cut the interlocking tongue-aud-groovejoints in the ends of the said box-sections. The sections after passing the saws g are fed through the curved portion of the extension of the channel a, and in passing this curved portion they are fed sidewise, but are turned from vertical to horizontally-disposed positions. Said box-sections being fed in close engagement through the said curved section are prevented from becoming mixed or losing their proper relation to each other, and this result is further insured by the retaining-spring t, (see Figs. 3 and 5,) which spring engages the adjacent ends of said sections and forces the opposite ends thereof against the opposite guide chamher It, thereby frictionally holding the stack of sections wherever set or left by the previous feed movement of the feed-head c acting through the intermediate box-sections in the channel a. If after passing the springt the box-sections were permitted to drop one by one, they would in falling turn edgewise and not be properly delivered to the bottom of the guide-channel. To obviate this action, the device previously indicated,and the operation of which will now be described, has been provided. When the feed-head 0 moves toward the saws bin the feeding action, the boX-section which stands immediately above the inturned lips t of the trip-springs 25 will engage the said lips and force the blocks t downward against the tension of thesprings 15 As the said feed-head c closely approaches the limit of its extreme movement the cam t on the shaft 25 will strike the cam-lever 25 and force the wedge 15 between the inner ends of the plunger-sections t, thereby forcing said plunger-sections outward against the tension of their springs i. As the finger portions i of the trip-springs t are of sufficient vertical extent to always stand in line with the outer endsof the plunger-sections t the outward movements of said plunger-sec tions will engage the same and force said tripsprings i outward far enough to carry their lips i? from under the engaged box-section. This being done, all of those box-sections which were forced below the tension-springt will drop together to the bottom of the guidechann'el, while the box-sections engaged by the said tension-spring will be held in position until forced below the same by the next feed movement of the feed-head c. The sliding blocks and parts carried thereby being released, as above described, will be immediately thrown upward to their normal positions by their springs 25 As clearly shown in Fig. 2, the sprocket m on the shaft is much smaller than the sprocket n. In practice the difference in the size of the said sprockets would usually be much greater than in the illustration given in the drawings. Hence it of course follows that the ejector or dischargehead m m will be reciprocated several times while the feedhead a is being reciprocated once. Each reciprocation of the ejector or discharge-head ejects edgewise one of the box-sections, and as this ejector may be run at a very high rate of speed and, further, as the speed of the ejector is the only limitation on the speed of the machine it of course follows that a machine of high efficiency or of great speed capacity is made possible. As the operator can collect a quantity of blank strips to be fed to the machine by one operation, it is not of course necessary for him to supply strips to the machine at each reciprocation of the feedhead c. He is therefore given more time to collect and properly select the blanks, and with less effort by the operator the machine will turn out a great deal larger amount of Work than would be possible with any ma chine constructed to feed but a single blankor strip at each feed movement.

The machine above described is of course capable of many modifications within the scope of my invention.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. The combination with a guide-channel through which the box-sections are fed flat wise, of a feed device driven relatively slow and adapted to feed a plurality of sections llatwise into said channel, at each feed movement, box-section-forming mechanism acting on said sections as they are passed through said channel, an ejector driven relatively fast and arranged to eject the box-sections edge wise, one at a time, and cutters acting upon said sections as they are ejected, substantially as described.

2. The combination with a horizontally-e16 tended guide-channel having a downturned ICC delivery-section, of a feed-head reciprocator longitudinally of and at the receiving end of said, channel, an ejector reciprocating trans versely of and at the lower end of said downturned channel-section, which channel passes said box-sections flatwise, and which feed device is adapted to deliver a plurality of said sections flatwise to said channel, and sectionforming cutters operating upon said box-seciions while they are subject to the said feed device and ejector, substantially as described.

3. The combination with a horizontally-extended guide-cl1annel having a downturned delivery-section, of a feeding device operating to feed the box-sections iatwise into and through said guide-channel, section-forming cutters operating on the box-sections as they are passed through said channel, a springpressed section holder or carrier acting upon the sections in the downturned portion of said channel, and a trip for releasing said sectionholder, substantially as described.

4;. In a machine of the character described, the combination with an upright guide chan nel or section through which the box-sections are fed fiatwise, of a box-section carrier or support yieldingly held upward but adapted to be depressed, and an automatic trip for releasing the same to permit the return movement thereof after having been depressed, substantially as described.

5. The combination with a horizon tally-extended guide-channel having a downturned delivery end, of a relatively-slow feed device delivering box -sections flatwise into said guide-channel, a relatively-fast ejecting de vice working transversely of the downturned delivery end of said guide-channel for discharging the sections edgewise, cutters operating on the sections as they are passed through said guide-channel, a friction device engaging the slats in the downturned portion CHARLES MONDENG.
